Applications complying with Apple's sandboxing rules for OS X havebegun to appear on the Mac App Store, with Pixelmator being amongthe first major offerings to meet the forthcoming requirement. Pixelmator version 2.0.4 was released on the Mac App Store (iTunes link) on Thursday, and as noted by Jim Dalrymple of The Loop , the release notes from the development team reveal that theupdate enables sandboxing support for OS X Lion. Pixelmator is aneasy-to-use image editor that sells for $29.99. The June 1 deadline for Mac App Store applications to meet Apple'ssandboxing requirement is fast approaching. |
The deadline wasextended to June 1 in February to allow developers more time to comply with the new rule. Originally, developers were required to have their applicationsready for sandboxing when the Mac App Store first launched in early2011. But Apple opted to give developers a reprieve until lastNovember, and again pushed the deadline back twice: once to March1, and another time to the current June 1 deadline. Sandboxing represents Apple's push to make the Mac platform more secure by restricting what applications are allowed to do within theoperating system.
This will help to prevent problems like malwaretaking over third-party applications. Some developers have been resistant to the changes that Apple ispushing, and have even discovered security flaws within the system before its official public launch. While the Pixelmator update will make it compatible with Sandboxingin Lion, the new security feature will play an even greater rolelater this year, when Apple launches its next-generation operatingsystem, OS X 10.8 Mountain Lion. One of Mountain Lion's biggestfeatures is Gatekeeper, which will give users the option to restrict a Mac to install only Apple-authorized applications from the MacApp Store. Gatekeeper will also allow users to restrict the installation ofthird-party software from outside the Mac App Store to onlyapplications created by identified developers.
Apple will provideits authorized developers with a secret key, and that key can berevoked if developers are found to violate Apple's terms. Though sandboxing will be required of all Mac App Store software,the Gatekeeper functionality in Mountain Lion will be optional. Ifthey so choose, users will be able to allow applications on theirsystem that are downloaded from anywhere, regardless of whetherthey are authorized by Apple.
